In this model, as in the previous model, the experimental constraints of a possible neutrino electric charge imply that \(\phi \approx 0\) . However, the definition in Eq. (REF ) is replaced by [1]}:
\(\tan \phi =\bar{\epsilon },\;\;\; \tan 2\psi =\frac{2s_WM^2_Z\tan \phi }{M^2_V-M^2_Z+(M^2_V-M^2_Z-M^2_W)\bar{\epsilon }^2}\)
